Around 1810 hours, while the Squad and Tower 3 were operating at a vehicle fire call on Interstate 83, Box 1-4 toned for a reported structure fire at 1253 Kittatinny Street. Squad 8 arrived with a working fire in a 3 story, occupied, end-of-the-row dwelling. Fire involved the first and second floors quickly resulting in the first alarm assignment. Several lines were stretched into the fire building and additional units stretched lines into the exposure. Companies were able to make a good knock on the fire in about 15 minutes. Extensive overhaul operations were required as part of the rear of the fire building collapsed.
